MICHAEL, Jemima TN>AL>MS>IL

I am searching for the parents of Jemima MICHAEL b. 3 March 1825 in TN.She married Baless Wood about 1840. We first found them on the 1850 Tishimingo Co. MS census, then in Massac Co. IL in 1860.This couple had 13 children.I have a lot of information on the children, none on Jemima or Baless before 1850.I would be grateful for any information.B L STRODER
